Emmi@ Feb. Iii QIIIIL mit COMBINED SHCKLE Ail SHOGK-QBSORBE application am i, 1917'.

To all 'whom t may 'concern Be it known that L OTTO E. Evans, a citi zen of the nited States, residing; at York.

Specification `of Letters Haccnt.

in the county of York and State of lie` hraska, have invented certain new and use*- fnl Improvements in Combined Shackies and Shock-Alisorhers, of which the follow, ine is a specification.

My invention relates to a combined spring' shackle and shock absorber.

An important object oit' the invent-.ion is to provide a device of the above mentioned character, which Will talre'up slight vibrations in. a highly efficient manner.

A further object of the invention is to provide deviee of the above mentioned character, which is simple in construction7 inexpensive 'to manufacture, strong and dnrahle.

@ther objects and advantages of the invention Will oe apparent during the coarse of the yfollowing description.

in the accompanying drawings forming' a part of this specification andy in which like `numerals are employed to designate like parte throughout the same,

Figure l is an edge elevation of a device embodying my invention, Fig. 2 is a side elevation oi? the saine,- Fig. 3 is. a longitudinal sectional View taken on line 3-3 of Fig'. l, and7 Ll is a transverse sectional view taken on line 4*-4 of Fig. 2.

in the drawings. wherein for the purpose l illustration is shown a prefer-red einbodi nient ot my invention, the numeral 5 desierthe body portion of the shackle, which l.

hoev portion or frame comprises sides tl, as shown.

lil'ear theirupper ends, the sides 6 are prrr vided with vertical elongated openingsA Tf., receiving an n n-per transverse boltS-r which is thereby adapted to partake oi slight vertical movements. A Washer 9 is 'preferably arranged between the head of the `loolt and one side 5 and a Washer l() is preferably arranged between the opposite side `5 and a nut 11 carried by theibolt- 8. The bolt 8 pivtaliy receives an eye l2 carried by one end of a elliptic spring 13.

erted approximately' tlshaped. This Serial No. lti.

The upper transverse portion ot the traine 5 is provided with depending flanges 15 receivingtherebetween a block of rubber 17 or.l member formed ot suitably elastic n'iaterial `The elastic member l? has its lower surface in Contact with the eye The sides 6 are provided near their ends with transverse openings iin receivingl a lower transverse bolt 19. having; a head :20, and a nut 21. Arranged between this' head and nut and the sides 6 are Washers 22, as shown. The holt 19 is provided Wim a lon g'itudinal opening or bore 23, passing through one end. thereof tor the reception .of a lubricant, such as This lnhri cant is suitablyy compressed 'hy means et a plunger 2li, operating therein moved inwardly by a sjrn'inggn 25 containing With a scieW-threaded pine' 26? as shown. YThe 'is provided with a laterally es discharge port 27, communicating," with t bore 23. Y

Pivotally receiving the holt 19 is an 2810i"- a elliptic sprintf dit is that the lubricant 'Within the bore will discharge between the eye 28 Iand the holt lil.-

lln operation, the weight ot the spring and its load, will be carried hy the elastie member i7, and associated elements7 Whereloy this elastic element Wili function to' taire eye lup or absorb slight shocks.

lt is to be understood that the 'form of rny invention herewith shown and descriloed is to be` taken as a preferred eitannile the.

joined claim.

Having thus descrihed my invention, 'l

claim: A conhined shackle and shriek' ahsmfioer. eoinprising an ap'iroxxmately "tl-'shaped traine havin s aoed sides connected 'h a transverse portion carrying' enaccd flanges,

for providing;- a pocket, said sides 'orovided with elongated openings extending longitudinally thereof, a bolt nionnted to vmove vertically Within the elongated openings and adapted for the reception oi the eye of a spring, an elastic block arranged holt apparent m www? 1n testimony whereof il .aix my signature in presence of two witnesses.

OTTO E. EVANS.

Within the pocket to Contact with one side of the eye, a bolt connected with. the spaced sides and provided with a longitudinal bore having a transverse port passing to the ex- Witnesses:

5 terior thereof, and spring pressed means for W. M. Ovnnsinnm, .compressing a. lubricant Within the bore. W. W. 1WYGKOFF.
